report on behalf of the SVOM team:
During the commissioning phase, a short burst from SGR 1E 1841-045 was detected during the routine on-ground search of the SVOM/GRM data at 2024-11-09T21:25:04.200 UT (T0), which was also detected by INTEGRAL/IBAS (GCN #38148).
The GRM light curve shows that this burst consists of a single pulse with a T90 ~ 0.1s.
The position of SGR 1E1841-045 is located at about 109.3 degrees from the SVOM optical axis, and outside the ECLAIRs field of view. At the time of the event, ECLAIRs was not collecting data.
The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA, China), National Center for Space Studies (CNES, France) and the Chinese Academy of Sciences (CAS, China), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. GRM is developed by the Institute of High Energy Physics (IHEP) of CAS.
The SVOM point of contact for this burst is: Wen-Long Zhang (IHEP)(zhangwl@ihep.ac.cn)
